Dr. John La Puma discusses how everyday environmental choices shape sleep, cognition, and long-term health. Drawing on research from medicine, neuroscience, and environmental science, he explains why many professionals unknowingly experience what he calls “cognitive drag,” the gradual decline in mental clarity caused by indoor lifestyles, poor light exposure, and excessive screen use. A central theme of the conversation is the biological importance of natural light. Morning sunlight triggers a cortisol activation signal that helps set the body’s circadian rhythm and supports deep sleep later in the night. Without that signal, the cycle of melatonin release and restorative sleep becomes…

Developing a sustainable and realistic competitive and comparative advantage in your career is challenging. Everyone reading this understands how difficult and tiresome it is to upgrade your profile and skill set so that you remain attractive to your organization and clients day after day, week after week, and year after year. And it is not just about being better than you were 12 months ago. It means being attractive relative to your peers and competitors. Each year, thousands of MBAs and other graduates enter the workforce with fabulous credentials, and your peers get staffed onto choice assignments close to the…

Julia Dhar, Managing Director at Boston Consulting Group and founder of the firm’s Behavioral Science Lab, joins us to discuss why most organizational change efforts fail and what leaders can do differently. Drawing on behavioral science and her work advising major organizations, she explains why the challenge of change is rarely about strategy alone and more often about human behavior.  Julia begins with a simple but powerful discipline used by many successful consultants: asking two questions repeatedly. First, “what is true about this situation?” and second, “what do I believe is true because of my perspective?” Confusing facts with assumptions…

Dr. Majid Fotuhi, neurologist, neuroscientist, and adjunct professor at Johns Hopkins University, has spent decades studying how the brain ages and what determines whether cognitive performance declines or strengthens over time. In this discussion, he challenges one of the most widely accepted assumptions about aging: that deterioration of memory and thinking is inevitable. The evidence, he explains, points in a different direction. Cognitive health is strongly shaped by daily choices, and meaningful improvements can occur within weeks when those choices change.  Fotuhi organizes the science of cognitive resilience around five pillars: exercise, sleep, nutrition, stress management, and brain training. Each…

Nidhi Tewari, a highly sought after wellbeing and work culture speaker who applies her experience as a licensed therapist to the work world, has spent more than a decade advising high-performing leaders on burnout, trauma, communication, and work culture. In this conversation, she brings a clinician’s precision to a topic many organizations still treat superficially: why capable professionals disengage, shut down, or burn out and what leaders can do differently. Tewari’s perspective is grounded in personal experience. After burning out multiple times and experiencing the sudden loss of her best friend, she recognized that burnout is not only psychological but…

Lorraine Marchand, startup CEO, advisor to Johnson & Johnson, member of the Pharmaceutical Advisory Board at Columbia Business School, and faculty at Wharton, discusses how leaders can sustain growth through disciplined experimentation in an era shaped by AI and institutional risk aversion. Marchand’s perspective is grounded in a career that spans large corporations and entrepreneurial ventures. Early in life, she learned to treat problem solving as an experiment rather than a test of personal worth. That principle later informed her approach to innovation in complex organizations. Several practical themes emerge from the discussion: 1. Reframe failure as structured learning. Marchand’s…

Dr. Guy Winch explains why we must treat emotional injuries with the same urgency as physical ones. “We ruminate, we beat ourselves up, we criticize ourselves, we think we’re weak… and we end up compounding the emotional injury.” He introduces the idea of “emotional first aid” and why we need a psychological toolbox to stop that downward spiral. Guy breaks down the difference between how we respond to physical pain versus emotional pain. “We go to the medicine cabinet for a physical injury, but we have no cabinet for emotional injuries.” He explains why we must learn emotional hygiene: “The…

Ashley Herd, former Head of HR North America at McKinsey, joins this episode to discuss what effective leadership looks like in practice, especially in environments defined by speed, pressure, and increasing expectations around AI. Drawing on her experience training more than 250,000 managers, she introduces a simple but rigorous framework: pause, consider, act. In fast-moving organizations, leaders often default to speed over reflection. Herd argues that the brief pause before responding to a mistake, delivering feedback, or making a decision materially changes outcomes. It allows leaders to ask: What result am I trying to achieve? How would I want to…

John McGinnis, law professor at Northwestern University and author of Why Democracy Needs the Rich, examines constitutional design, democratic stability, and the accelerating force of artificial intelligence. Drawing on the Federalist Papers, Tocqueville, and public choice theory, he argues that a realistic understanding of politics is essential to preserving both liberty and effective state capacity. McGinnis traces his intellectual formation to a “hard-headed realism” learned early in life and later reinforced by the American founding. At the center of his thinking is a practical constitutional question: how to build sufficient state capacity while preventing its abuse. He emphasizes the importance…
